# Slackware build script for ds-models

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Note to self: find and package a decent model pack that works
# properly with current gzdoom versions. If such a thing exists.
# Initial searching and testing indicates maybe not...

# 20211103 bkw: BUILD=4
# - fix script being installed to nonexistant /usr/games.
# - remove gzdoom support, since neither gzdoom nor gzdoom-legacy
#   works with these models.

# 20160810 bkw:
# - bump BUILD because:
# - install scripts in /usr/games, not /usr/bin

# 20140324 bkw:
# Updated for version r15
# fixed typos in README
# fixed .def files for recent gzdoom
